It was reported by Russian media that the RuAF were carrying R-74 in Syria. I believe after the shoot down of the Su-24M by Turkey it was announced that all Su-34 and Su-30SM performing strike missions would also carry A2A missiles, R-74 named in particular.
Meanwhile it's reported that there is a clean sheet design in development to completely replace the Archer family on Su-35, Su-57, MiG-35 and future aircraft. Not to mention further R-74 development for the shorter term with LOAL and INS initial guidance to allow over the shoulder launches/attack targets designated by other aircraft. Thereby matching the capabilities of the latest AIM-9/MICA-IR/IRIS-T variants.
